Electrical engineer here. You are just wrong. Outright, utterly wrong. You have absolutely no idea what you are talking about. You are confusing the part of the spectrum that has frequencies in ultraviolet and above, which is cancer causing, with the frequency spectrums used in communications, which are all far below visible light, let alone ultraviolet. Ultraviolet is the invisible, and highest frequency part of sunlight, and can give you skin cancer. Higher frequencies than that include x-rays, gamma rays (from nuclear reactions), and cosmic rays (which are almost entirely blocked by the earth's atmosphere), all of which can also give you cancer. Visible light, and all the communications spectrum, are all of lower frequencies than ultraviolet, and can't give you cancer. That said, the spectrum below ultraviolet can cook you, but it has to be insanely higher energy levels than what is used in telecommunications (eg using a magnifying glass to magnify sunlight, or sticking your head inside a microwave oven (note: microwave ovens are definitely high enough power to cook you, but they are surrounded by a faraday cage - that metal grill covering the door, and the metal cage around the back and sides - which in the case of microwave frequency, the microwaves can't pass through a metal shield with holes smaller than 12cm diameter (the wavelength of typical microwaves in an oven)), or standing right next to the amplifier inside the generation room under a TV tower when it is turned on (it has to be turned off for anyone to do any maintenance work on it, and is locked out when it is turned on. The energy levels decrease by the inverse square law, so the energy levels quickly become very small by distance, and are completely safe after a certain distance)). Every single iteration of mobile phones has come with people worried about cancer, but it is all rubbish, and as you see around you, people aren't getting cancer from 1G, 2G, 3G, or 4G, and they won't from 5G either, or any other G after that.
